Answer 3

Let's solve each of these equations step by step:

1. 890 - 7 * 9 + 1: First, calculate the multiplication: 7 * 9 = 63 Then, perform the addition and subtraction: 890 - 63 + 1 = 827

2. 470 - 350 + 189: Perform the addition and subtraction: 470 - 350 + 189 = 309

3. 857 + 13 * 3: First, calculate the multiplication: 13 * 3 = 39 Then, perform the addition: 857 + 39 = 896

4. 1,000 - (259 + 711): First, calculate the addition inside the parentheses: 259 + 711 = 970 Then, perform the subtraction: 1,000 - 970 = 30

So, the results are as follows:

1. 890 - 7 * 9 + 1 = 827
2. 470 - 350 + 189 = 309
3. 857 + 13 * 3 = 896
4. 1,000 - (259 + 711) = 30
